# syntax=docker/dockerfile:1.7
#
# Multi-stage build for Rekey (api + panel + portal + admin).
#
# Stages:
#   base    — pnpm + corepack on a slim node image
#   deps    — installs ALL workspace deps (including dev) for building
#   build   — compiles api (tsc) + panel + portal + admin (next build)
#   runtime — copies built artifacts + production-only deps into a fresh
#             slim image. Each app is its own runtime stage; pick with `--target`.
#
# Build:
#   docker build -t rekey-api .                          (default = api)
#   docker build -t rekey-panel --target=panel-runtime \
#     --build-arg NEXT_PUBLIC_API_URL=https://api.example.com \
#     --build-arg NEXT_PUBLIC_APP_URL=https://panel.example.com .
#   (NEXT_PUBLIC_* have no defaults — they compile into the bundle, so a default
#    would be a Rekey URL nobody could override at runtime. Marketing REQUIRES
#    both and its build fails without them, deliberately.)
#   docker build -t rekey-portal --target=portal-runtime .
#
# Or use docker-compose.yml which builds each with shared build cache.
#
# The api image runs `prisma migrate deploy` on start (idempotent) before
# booting the server, so a fresh database is migrated automatically.

# Install the api + shared-types dependency closure. We do NOT pass --prod and
# we set NODE_ENV=production only AFTER installing, so pnpm keeps the api's
# devDependencies — specifically the `prisma` CLI, needed to (a) generate the
# client and (b) run `migrate deploy` at boot. (`prisma generate` auto-tries
# `pnpm add prisma -D` when prisma is absent from devDependencies, which fails
# inside a workspace — so prisma must be a present devDependency, as in build.)

# Install deps, generate the Prisma client, and prune dev-only tooling — all in
# ONE layer. Reasons:
#   * No --prod / NODE_ENV unset here so pnpm keeps `prisma` (a devDependency),
#     needed to generate the client and run `migrate deploy` at boot. (`prisma
#     generate` auto-runs `pnpm add prisma -D` when prisma is missing from
#     devDependencies, which fails inside a workspace — so it must be present.)
#   * Generating here (not COPYing from build) avoids the pnpm peer-hash skew
#     that leaves a cross-stage client where the runtime symlink can't see it
#     ("@prisma/client did not initialize").
#   * The TypeScript/test/build toolchain (vitest, typescript, tsx, esbuild,
#     @types) is the heaviest devDep weight and the runtime never imports it.
#     Deleting it in the SAME RUN as the install keeps it out of the layer
#     entirely (a delete in a later layer wouldn't shrink the image). Prisma +
#     its engines stay.
